Yes. Try writing on a piece of paper with a pencil, then try writing on a piece of glass with the pencil. It's harder to write on the glass because there is less friction.

Assuming the rugosities are not so large to be trip hazards, the rough surface has the higher friction, hence drag, between floor and shoe sole.
abrasive means to smooth out a rough surface
the rough surface creates more friction as to that of soft surfaced ones
Smooth surface
The rough surface is better than the smooth surface for the frictional force to act.

No. Rough surfaces makes the ride bumpy, notchy and rough. You might even fall. You want smooth, but not slippery, for a good ride surface.

Its surface is rough because of all the rock's and crater's in its surface.

no zinc is not rough it's surface is smooth
because all the crystals in the substance are facing the same direction. they are all little mirrors by themselves
mars is rough because of it craters
The Rough ER has a surface covered by mitochondria - which appear as small circles, and make the surface "rough" in appearance. The Smooth ER does not have these ribosomes, and so the surface is just one smooth line.
